Miniature linear guides are compact-sized and highly precise linear guide systems, applied in fields such as the microelectronics industry, medical devices, and precision measuring instruments.
1. Application Conditions
Linear Guideways are widely used in various scenarios, but the selection of micro linear guides is directly affected by different types of machine tools and machining accuracies:
For machine tools with low machining accuracy (such as rough equipment), sliders with larger sizes are usually required. Although these sliders have strong load-bearing capacity, they are heavy and lack flexibility.
Conversely, machine tools with high machining accuracy require higher linear rail accuracy. Therefore, it is necessary to select guide rails with appropriate accuracy grades to ensure motion stability and control machining errors.
2. Load Capacity
As the core component of mini linear guides, the selection of sliders is directly related to the accuracy of the linear guide rails, and the following key points need to be carefully considered:
1) Load Threshold: The maximum load-bearing capacity of the slider is a key indicator that should be matched to the actual load requirements of the equipment.
2) Safety Factor: The safety factor design of the linear rail system determines the redundant space of the load capacity. A high safety factor can enhance the reliability of the equipment's long-term operation.
3. Expected Service Life
The expected service life is an important factor affecting the price of micro linear guideways, specifically reflected in:
The length of service life directly reflects the material quality, structural design, and wear resistance of the guide rails.
When purchasing, it is essential to consult the supplier explicitly about the expected service life of the product and receive their maintenance suggestions to balance cost and usage requirements.
